How the SERVIR program connects space to village

Dan Irwin, director and founder of SERVIR, chose the name of the program from the Spanish and French verbs meaning “to serve.” As Dan explained in his recent TED Talk about SERVIR, we don’t want to miss seeing the forest for the trees — that is, capturing details via space that are almost impossible to decipher here on the ground. SERVIR connects directly with people at various levels, from international groups to local partners to do just that — serving society with science and technology, connecting space to village.

Connecting satellites to life here on Earth

Google Earth Engine is one of the tools that helps SERVIR put the power of satellite information into the hands of local people by improving access to data and reducing barriers to conducting research, especially in regions with limited bandwidth.

With access to heaps of data, it’s critical to avoid burying local researchers and government workers in information without providing the support to interpret and explain its relevance. This is why assessing user needs is a vital first step. SERVIR hub scientists work alongside local stakeholders to identify ongoing challenges, organize in-region workshops and hundreds of training events such as Advanced Google Earth Engine training for forest and river monitoring, and co-develop relevant tools and services with NASA and USAID support.

SERVIR projects around the world

The SERVIR network is now able to create specific web applications that provide access to Google’s cloud-based multi-petabyte catalog of satellite imagery and geospatial datasets — helping people make decisions involving weather, land cover and land use, water resources, food security, and disaster management in-region.

Supporting flood emergency preparedness for Myanmar

Myanmar suffers from devastating flooding on a regular basis — including sudden-onset flash floods. Emergency response personnel need help with pre-planning to ensure the availability of supplies and shelters. SERVIR-Mekong, which helps countries in the Lower Mekong Region, developed a flood risk decision-support tool using Earth Engine and surface water maps derived from 30 years of Landsat imagery. With this tool, variable risk for floods and potentially for droughts can be found with the identification of areas particularly prone to such disasters.

Mapping wheat area in Afghanistan

Wheat is a major crop and staple food for Afghanistan. However, wheat productivity is hampered by poor irrigation systems, droughts, changing farming practices, and crop disease. Even though Afghanistan is a significant producer of wheat, it still imports the cereal from other countries. SERVIR’s Afghanistan Wheat Mapping Application allows users to generate maps for wheat-growing areas in irrigated and rain-fed land parcels at the provincial or national level in Afghanistan. The maps help create timely forecasts of wheat production, which are useful for planning and ensuring food security when shortages are predicted.

Tracking forest fires in Bolivia

The 2019 fire season in Bolivia included numerous and intense fires in the country’s Amazonian dry forests and savannas. Bolivia urgently needs real-time monitoring of active fires to support ongoing fire management efforts at the national level. SERVIR developed the Amazon Fires — Bolivia tool, which compares data about pollutant particles trapped in the air to recent satellite images to plot the locations of fires in near-real-time.

History in the making

SERVIR’s connection to Google Earth Engine goes back over a decade. At Brazil’s National Space Research Institute meeting in 2009, Emil Cherrington was in attendance for the final meeting day where Rebecca Moore, Director of Engineering at Google, made a bold proposition: What if the processing algorithms for mapping forests — and the input NASA satellite data — could be placed on Google’s servers for countries to do their forest monitoring?

The proposition seemed ambitious and yet, a year and a half after the meeting, Google Earth Engine was officially released in late 2010. Almost 10 years later, the platform has expanded in focus, applying Earth observation data to address environmental and social issues. Over the past 15 years, the SERVIR program has empowered more than 3,500 people in 50 countries to use satellite data through hands-on events, trainings, and the creation of tools and applications.
